With the proper pond maintainance koi live for several year and even decades and get very big in size. Follow these tips to build your koi pond properly so your koi fish will live and multiply.
Make your pond deep
Depth of your pond is very important. The minimum recommended depth is 4 feet, however it is is a good idea to give your fish six or even 8 feet deep pond. This will ensure that your fish are protected from raccoons, pet kitties and other animals who love a fish dinner. Deeper fish pond also helps to keep water cool in summer months
Give them space
Small ponds are not appropriate for koi. Remember, with time koi can grow quite large and they will need a lot of room. Also there are so many color variations of koi, that with time you will probably want to add more fish to your pond. So it is better to create a large garden pond from the start than rebuild it later. About ten thousand gallons is suitable for a backyard pond with fish , bigger would be even better.
Provide some heating in colder months
Unlike tropical fish, koi don’t suffer much from cold; however you should never let your pond freeze completely. Installing a proper garden pond heater will always keep an opening in the ice. Also keep in mind, that koi fish only grow when the water is warm, so with a heater your fish will grow faster
Provide some shade for your koi
When selecting where to place your pond, make sure it is out of direct sunlight. Also keeping water plants like water lilies in your pond can be very beneficial – not only they add beauty to the overall look of your pond, but they also provide shade for the fish. However, you should avoid building your koi pond under trees. Cleaning a fish pond of fallen leaves is no fun.
Plan to install a bird net
There are many birds of prey that would eat your koi. Don’t give them the opportunity; plan your pond location so it is possible to protect it with a net.
Keep insecticides away from your pond
When landscaping your pond keep in mind that you should not use any insecticides or herbicides near the water. Even a small amount of common garden poison can make sick and possibly kill your beautiful fish.
Pumps, filtration systems and other fish pond accessories
Several accessories are absolutely essential for a healthy koi pond. Ideally you should get a water pump, filtration system, pond water aerator and an ultraviolet sterilizer. If the water in your pond is not moving, your koi might feel unwell. Koi pond filtration systems are pricey, so as an alternative you can make your own homemade filters.
